See if you agree with my noddy calculations of if I leave a 10W device on ALL YEAR 24/7...

I believe electricy costs around 12 pence per kWH?

So a noddy calculation equates to:-
12*10/1000=0.12p per hour?
0.12*24=2.88p per day?
2.88*365=£10.51 per year?
 
Pretty sure thats right. Cant see how it would be a decimal place out, as neither £1.05 or £105 would be correct for a 10W item!
 
So question then, how much would it cost to run a computer for about 6 hours a night, computer including monitor and speakers as well. My parents make a big fuss about shutting down while I go for dinner for like 20 minutes downstairs, when I don't really see a problem with it?
 
Use the sleep function if after 5mins no activiuty it sleeps, keyboard press and you back to where you were in 3secs.....

Can you make that a little more vague please?

Try something like 'How much to run stuff for some time?'


;)

If you search GH this question comes up fairly often. How much do you pay towards the electricity bill?

It annoys me when my house mates come down for dinner and leave their xbox on, dont even turn the tele off!
 
A LCD monitor is about 50w, and a PC at rest is probably around 250w. Call it 300w total. So using 12p per kwh, 20 minutes would cost you about 1.2p. Or about a fiver a year if you did it ever night.
 
20 Minutes might not sound like a lot, but if it is 20 minutes say 6 days a week, that's 120 Minutes or 2 Hours your PC [and speakers etc] has been sat there doing not a lot.

Two hours is probably nothing on its own but all the little things add up. I bet you don't leave your PC for just 20 Minutes a day doing nothing. For the sake of waiting a few seconds to wake up from sleep it is worth the energy saving. You can set it to go into Sleep all on its own, so even less effort.

The question shouldn't be "how bad could it be?" it should be "how much better can I make it?".
 
Don't forget to calculate the offset in heating caused by the PC, and also the cost of 'your time' while you wait for it to come out of sleep, all those times. Over the year it adds up. And stuff.

The problem with this argument is time isn't magically stored up for later use. It's not like the hour you saved by not shutting down your PC is waiting for you at the end of the year.

The 5 seconds you "wasted" waiting for your PC to wakeup is 5 seconds out of one day. Hell, it is 5 seconds out of one hour. What exactly are you going to do in that time? If you are concerned about those 5 seconds, go to bed 5 seconds later.
 
Yeah, Hibernation copies the contents of RAM to the HDD. It takes longer to boot as it has to write it all back into RAM. Sleep mode keeps everything in RAM and turns off everything else.
 
This is very true, cheers guys :)
Suppose a sleep would be the best thing to do really, I do turn my monitor off and TV if it's on in the first place, I was just curious as to how much it costs to run something like a PC for one night's useage, that's all :)
 
I think it's very, very important for us all that nobody works out how much it costs to run a gaming pc 24/7/365!
